Handspring, Inc. released a GPRS <A HREF="http://www.t-mobile.com/treoupgrade">software upgrade</A> for Treo customers using T-Mobile wireless service in the United States. This user-installable software upgrade is designed to enhance applications like email and Web with faster, persistent connections to high-speed data networks. The upgrade also includes improvements to the phone and SMS applications as well. In addition to enabling the Treo 180 and 270 to take advantage of high-speed data networks, Handspring's GPRS upgrade includes a number of software enhancements. With the upgrade, Treo automatically becomes configured for data access--there is no need for manual configurations or an Internet Service Provider (ISP). In the SMS application, Web pages can be launched, phone numbers dialed, and emails addressed by tapping the corresponding information (URL, phone number, or email address) that arrives in a text message. There is also a new Mute button as well as keyboard hints built into the phone application.
